Living up to DARPA's original goal of developing a robot that could outrun any human, the quadruped robot has set a new robotic land speed record of 28.3 mph (45.5 km/h) for a 20-meter (65.6 ft) split, bettering Bolt’s human speed record by 0.52 mph (0.8 km/h) and breaking its own previous record of 18 mph (28.9 km/h) set earlier this year.
